JOHN MARQUIS, OF SAN FRANCISCO, CALIFORNIA, ASSIGNOR TO IIIMSELF AND JOHN J. NEWSOM.

IMPROVEMENT IN WATER-CLOSET REGULATORS.

Specification forming part of Letters Patent No. 142510, dated February 17, 1874; application filed November 12, 1873.

To all whom it may concern:

Beit known that I, JOHN MARQUIS, of San Francisco, in the county of San Francisco and State of California, have invented an Improved Tater-Regulator mainly adapted to Tater- Closets; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompany'- ing drawings and to the letters of reference marked thereon.

The object of my invention is to provide an improved device for regulating and measuring the flow of water employed vin water-closets; and it consists ot acylinder otl suitable capacity having a closelytting piston, and also provided with water-passages leading from either end of the cylinder to a valve-chamber, in which moves a valve so operated as to cause one end and the other ot' the cylinder to iill alternately. As one end is illing with water the opposite end is being discharged by the pressure through suitable passages in'to the bowl.

Referring to the accompanying drawings for a more complete explanation of my invention, the figure shows a side sectional elevation ot' the regulator.

H H are the spaces above and below the piston, respectively, in a cylinderof such a size. as to hold a sufficient quantity of water to thoroughly cleanse the bowl. Ihe piston E is packed, so as to lit l and move closely within the cylinder; and this piston is fitted with leather caps or packing b at each end, which serve to close the ports K K whenever the piston arrives at either end. These ports comthe ports C C.

the eductionport discharging into the bowl The valve I) may be balanced, rotary, or other suitable form, but I have employed in the present case the ordinary slide-valve with a stem, a. extending up through the upper end of the valvebox, being suitably packed. This rod may be operated by hand, or by a persons weight, as desired, or the valve may have a spring which will keep it forced in one direction, while, by the hand or pressure, it can be moved in the other.

The operation will be as follows: The water entering beneath the valve through the passage B passes through the port C into the passage A, and thence through the opening K into the cylinder above the piston E. The pressure forces the piston to the lower end of the cylinder, driving out the water that had previously entered below, when the valve is moved Vto its other position. This water passes out through the opening K and up the passa-ge A', thence through the port C', and out at F into the bowl.

By this arrangement the amount of wa'ter used can be regulated, andit will not be possible to tamper with the 1naehineso as to cause the water to tiow all the time.

Having thus described my invention, what K K', passages A A, ports :l and F, and valve,

constructed and arranged in relation to each other, as described.

In witness whereof:l I have hereunto set my hand and seal.
